Superthin spark plug socket for inner plugs

Im starting to really hate this bike.

So while diagnosing the fuel leak I am trying to replace the inner plugs but my regular thin walled spark plug wrench that works on every other vehicle I have ever owned is too thick for the Griso. It looks like you get about a MM of metal available to support the walls of the socket.

Is there a place I can actually buy one that thin?

I believe the socket is available from Moto Guzzi but I got a standard plug socket taken down on a friends lathe, works fine.

Did the same with a stationary grinder. Just took some off, checked fit, took more off if needed. I wanted to keep the socket as strong as possible. I've heard of the special tool from Guzzi being a little fragile and failing.

Its asinine that it requires the thinnest socket known to man, there is no reason to make that portion so tight.

Perhaps.

OTOH, as someone who has littered the ground with broken lances in front of many a windmill :think:, I can't criticize your passion, but as the fix is pretty easy and cheap, not sure it's worth much angst. A curse or two is, of course, authorized and probably therapeutic. :swear::)

One more crumb for thought food. While already "in there," it's not a bad idea check to ensure that the inner plugs don't corrode themselves into place (and then prevent same with a modest amount of anti-seize). That said, the R&R intervals for those plugs is, IMO (and observation on my Griso & Norge), way too short. Someone in Mandello must own stock in NGK. ;)

That is a second post for that socket. Did it work without grinding it down? It looks like that model might be sold at my local big box retailer. Ill be good for a bit but I dont want to be in the same situation where I go out to work on the bike and find out I cant do it because of a stupid tool.

I managed to get them out. A friend had one already ground down. And don't worry Bill, a cleaning, copper anti-seize, and dielectric grease accompanies EVERY spark plug change I have ever done (side note, copper is for electrical connections but metal free is great for keeping wheels from fusing to hubs).

Howdy ... again.

As for fitting without grinding, cannot confirm for all Guzzi applications, but it easily fits my Norge. It's irrelevant on my EV, and have not needed yet on Griso.

I am in Atlanta every month for a week or so -- next there 9 - c.18 March. Not sure where you are in the kudzu metroblob, but happy to bring that socket along for you to see about fit. It'll cost you a beer. ;)

Thanks but I'm actually good. A friend brought over his ground down model and it looks like a KTM forged one fits as well so I should be covered.

Although we could still meet up for a beer.
